Patented June 24, 1930 PATENT OFFECE ALBEN A. POTTER, OF MONTGOMERY COUNTY, MARYLAND i cAsnMENr Application filed September 26,1527. Serial No. 221,953.

My invention consists in a new and useful improvement in easements and is dei be used. The particularly novel and useful feature of my device is the means which I provide to permit the easement to be pivoted on its lower edge so that it may be partly opened at the top, and also permit it to be pivoted at its upper edge so that it may be fully opened. In my device, l have provided a swinging easement which may also be slid relative to its frame, a novel feature in these devices.

While I have illustrated in the drawings filed herewith, and have herein fully described one specific embodiment of my invention, it is to be distinctly understood that I contemplate many other embodiments, do not consider the invention limited to the specific embodiment herein illustrated and described, but refer for the scope of my invention to the claims appended hereto.

In the drawings:

Fig. 1 is front elevation of the easement, parts shown in normal position.

Fig. 2 is a similar view, parts shown in adjusted position.

Fig. 3 is a vertical section, the easement being shown in full lines in one open position, and shown in dotted lines in closed position shown in Fig. l.

Fig. 4 is a vertical section, the easement being shown in full lines in another open position, and shown in dotted lines in closed position shown in Fig. 2.

Fig. 5 is an enlarged vertical section, on

line 5-5 of Fig. 6.

Fig. 6 is an enlarged horizontal section, on line 6-6 of Fig. l.

In the specific embodiment of my invention illustrated in the drawings, I have shown a frame F for the easement, having a sill l, a stool 2, a top apron 3, and side stops 4. The easement C is received in the frame F and normally rests upon the sill 1, outside of the stool 2 and inside of the apron 3 and side stops 4, as shown in Fig. 1, and in dotted lines in Fig. 3. The side members 5 of the easement C are provided at their upper parts with rabbeted portions 6 in which are received, when the casement C is in normal position, slotted arms 7 carried by bolts 8 in the upper part of the frame F adjacent the apron 3. Pins 9 in the side members 5 serve to effect a slotand-pin connection between the easement C and the frame F, through the arms 7 pivoted on the bolts 8. Adjacent the bottom of the rabbeted portions 6,'each sidemember 5 is provided with a mortised boltlO having a rack 11 with which meshes a pinion 12 on a mortised 'shaft 13 having an operating knob 14 projecting from the inner face of the side member 5. The frame F is provided with suitably disposed sockets 15` for receiving the ends of the bolts 10. They bolts 10 and sockets 15 may be complementarily obliquely faced, so that when the bolts 10 are received into the sockets 7 15 they serve to clamp the easement C against the apron 3 and side stops 4 in the frame F. It is to be noted that the slotted arms 7, bolts 10 and sockets 15 are s o disposed in relation to one another that when the easement C is in normal position, as shown in Fig. 1, the bolts 10 register with the sockets 415, and may be received therein, and that when the easement C is slightly raised so as to clear the stool 2, as indicated inFig. 2, the bolts 10 register with the lower extremities of the slots in the arms 7 and may be received therein. `At the upper edge of each rabbeted portion 6 in the side members 5 of the easement C, I provide a semi-circular recess 16 into which is received the head of the bolt 8, when the easement C is raised, as shown in Fig. 2. I have also illustrated (though no part of my invention) a netted screen 17 applied to the youtside of the frame F, to indicate that the opening may be covered by a permanently attached outer screen, withr which there will be no interference by the manipulation of my improved casement.

From the foregoing description of the details of construction of my device, its operation and use will be obvious. When the parts are in normal position, as shownin Fig. 1, the` bolts 10 may be retracted by turning knobs 14, and the easement C, being released from the frame F, may be swung inwardly, pivoting on its lower edge resting on the sill l. The pins 9 slide in the slotted arms 7 until the ends of the slots are reached, and the arms 7 limit the movement of the Casement C, so that it assumes the position shown in full lines in Fig. 3. easement C is'in this position, it will beseen that ventilation( is afforded through the opening at the top of the easement C, without exposing the interior to the weather. It is also to be noted that the easement C can be adjusted for ventilation without disturb# ing the screen 17 v If it is desired to fully open the easement C, the parts vmay be adjusted as shown Vin Fig. 2, the easement -C being slid upwardly inthe frameF sufficiently to clear the stool 2. rilhe boltsflOgare projeotedto engage the klower ends of lthe arms 7 through the slotsI thereof. The easement -G isthussupported by the arms 7` which serve, with the boltsS, as hinges for the easement C. It may then be swung inwardly, and upwardly, pivoting at its upper edge to the vposition shown in` f ull'linesV in'Fig. 4:, being retained in. such position by Aany suitable fastening means.

Having described my invention, what I. claim is l. The combinationwith ya frame therefor of a Casement; means adapted to limit the movement of the Casement when it isv pivoted on its lower edge; and reciprocableV means adapted to co-act withA said limiting means to furnish a hinge for said easement at its upperedge.

2. ln a casement of a pivoted member; a permanent connecf tionrbetween said member and the easement; and a removable connection between they 4.'ln a Casement, the combination of a frame; a sash; slotted arms pivoted to said frame; pins on said-.sash receivedin the slots of said arms; sockets in said frame; and

bolts in said sash so disposed as to be alter.-

` nativelyreceived in said sockets and in the slots in said arms.

5. In combination with a frame therefor of a Casement; and means associated with said easement and frame, comprising manu- V to be swung relative to ysaid frame pivoting` at the bottom of said frame, and when lock? ed to permitsaid Casement to. he swung rela?v When the fixture, the combinationY tive to said frame pivoting at the top of said frame. f

6. A Casement provided with means for y adapted to secure said easement againstV longitudinal movement relative to said lim-VK iting means when the casementis pivoted at a point adjacent its upper edge.

In testimony whereof I affix my signature. Y
